The normal micro-architecture of trabecular bone at the distal tibia is evident in an image obtained using FIESTA_C and parallel imaging at 7T (right) on a GE Signa.
The normal micro-architecture of trabecular bone at the distal tibia is evident in an image obtained using FIESTA_C and parallel imaging at 7T (right) on a GE Signa. Studies at this field strength by Sharmila Majumdar, Ph.D., and the musculoskeletal and quantitative imaging research group at the University of California, San Francisco, emerged as a consequence of studies at 1.5T. Images at 1.5T of a patient with osteoporosis demonstrate the degradation of trabecular bone indicative of disease progression, according to group director Majumdar. This work is establishing the foundation on which she hopes to build MR as a noninvasive biopsy tool for gauging the strength of bone in patients suspected of osteoporosis. (Provided by S. Majumdar)
Could Ultrafast MRI Enhance Detection of Malignant Foci for Breast Cancer?
April 10th 2025In a new study involving over 120 women, nearly two-thirds of whom had a family history of breast cancer, ultrafast MRI findings revealed a 5 percent increase in malignancy risk for each second increase in the difference between lesion and background parenchymal enhancement (BPE) time to enhancement (TTE).
MRI Study Suggests Shape of White Matter Hyperintensities May Be Predictive of Cognitive Decline
April 7th 2025Emerging research demonstrated that cognitive declines in memory, executive function and processing speed domains were associated with irregular shape of periventricular/confluent white matter hyperintensities.
Can Abbreviated MRI Have an Impact in Rectal Cancer Staging?
April 4th 2025Abbreviated MRI demonstrated a 95.3 percent specificity for rectal cancer and provided strong agreement with the full MRI protocol for T staging and detection of extramural venous invasion, according to newly published research.
